| A17-6 | Coupled oscillators. |
| Purpose: | To show different modes of motion. |
| Description: | Two identical gliders are placed on a short air track. Springs are placed between the gliders and to the ends of the track. Different modes of motion can be shown. A high frequency is realized when the gliders move in opposition, and a lower frequency when they move with parallel velocities. |
